Is there a way to use a WORLD MATERIAL for lighting, and have another WORLD MATERIAL for visuals?
You can achieve this by mixing your 2 backgrounds (lighting and visuals) using the &quot;Is Camera Ray&quot; output of a Light Path Node. For your situation, plug the same image into both backgrounds, and alter the individual strengths of the Background Nodes (Hard to show what it's doing in an image, so I used red as one background instead for the example):

Though it's really hard to tell what the lighting's supposed to look like, I did my best to show which one is too bright and which one is too dark (for the example). Regardless, your setup should look something like this. Adjust the respective strengths to your liking:
